Question

Hi I have problems with my Toshiba inbuilt speakers. They Crackle, or sometimes no sound at all. I've tried everything from unistalling the sound driver and reinstalling. But the problem still occurs. I also did a system backup and did a system restore. Which took my system back to how I first brought it. But my speakers still crackl when I play anything. This is really frustrating and now I've found another problem with my audio output. It crackles and the sound comes not only from the inbuilt speakers but also from the speakers I have pluged into the laptop. Please help me Eric.
